New patch (v62)

Released a quick patch as I found one of my recent patches was causing out of sync errors for people in multiplayer. But also Alexandre the composer has added a couple of new music tracks for when you visit AI camps. Here's the changelist:

• Looter and Neutral Camp Music
  
• Fix for raiders getting stuck trying attack an inaccessible zombie
  
• Fix for combat AI sometimes getting stuck when inside a fence attacking a zombie outside it
  
• Fix for farmer AI getting stuck going into and out of a building repeatedly
  
• Fix for farmer AI not being getting water from bottles in nearby buildings
  
• Out of Sync fix
